Title: Remote angular position indicator for butterfly valve - uses potentiometer to control voltage measured by galvanometer
IPC: F02M19/01
Filed: 1974-04-19
Abstract: The butterfly valve (1) has its spindle (13) mechanically connected to a potentiometer (2) which is connected electrically to a battery (4) and a galvanometer (3). Pressure on the accelerator pedal rotates the butterfly spindle (13) and causes the arm (21) of the potentiometer to rotate. This motion varies the value of the resistance (24). This variation of resistance changes the voltage drop across the galvanometer (3) and this voltage which is registered on the scale (34) indicates the angular position of the butterfly valve. The vehicle driver is thus able to adjust the throttle to ensure that the degree of opening is no greater than is necessary and so improve the fuel consumption.

Title: Machine tool slide ways - oil is fed and regulated under press. to grooves in sliding member with boundary seal
IPC: F16C32/06
Filed: 1974-04-25
Abstract: The horizontal milling or boring machine head is arranged to slide vertically on a vertical member, which itself can slide on the bed (3). In the lower face (5) of the vertical member, which slides on the upper face (6) of the base (3), are openings (7), the bottom of which are joined by a pipe (8) to a source of oil under pressure (which can be regulated). The openings (7) are never open because the base of the vertical member is less than the length of the bed (3) on which it slides and the edge of the openings (7) has a seal. There are also grooves (12) in the side of the vertical members.

Title: Non-woven covering fabric for e.g. roofs - comprises filament layer between two fibre mats
IPC: D04H5/08
Filed: 1974-05-30
Abstract: A non-woven covering fabric is formed by depositing a first mat of fibres from a first hood onto a conveyor and then depositing from guide tubes a layer of parallel filaments and a layer of randomly deposited filaments onto the first layer of fibres. The conveyor is then advanced past a second hood into which short fibres are fed so that they fall onto the conveyor and fill the spaces between the filaments and into which fibres similar to the fibres of the first mat are fed to form a second mat of fibres over the filaments. The fabric is impregnated with bitumen to form e.g. a roof covering. The fabric may be left in sheet form are may be cut into tiles. The resulting impregnated sheet is stronger and more resistant to cracking esp. when bent in cold ambient conditions.

Title: Oil well packer - hydraulically set by wedge seals with shear pins and released by turn/pull
IPC: E21B33/1295
Filed: 1974-07-18
Abstract: An oil-bearing formation packer for oil wells consists of an upper part with a lower part which can be hydraulically actuated to rupture shear pins and apply annular wedges against the casing on either side of a rubber packing. To disengage the packer, an uncoupling part is turned and the application of a pulling force ruptures two other shear pins to allow slide-back protection sleeves to slide. The oil production tubing needs no manipulation to set the packer. The packer release device is protected against corrosion and clogging and remains functionally reliable for a release after it has remained set for several years.
Patent FR-2280712-A1 (FR)
Title: Deoxidation and carburization of steel melt - using powdered carbon and a triple duct tuyere
Inventor: BASTIEN JEAN
IPC: C22B5/10
Filed: 1974-08-02
Abstract: Method of deoxidation and/or carburisation of a bath of molten metal esp. steel by injection of powdered carbon or a powder contg. C by means of one or more submerged tuyeres, is characterised in that the tuyere comprises three concentric tubes, the central tube being supplied with neutral gas, or CO2 during the oxidation step(s) and with neutral gas carrying C powder during the deoxidation or carburising step, the intermediate tube is fed with oxygen during the oxidation step and a non-oxidising gas during the deoxidising step while the outer tube is fed with a fluid to protect the tuyere against wear during the oxidation steps. The use of a tuyere avoids problems associated with blowing in powder via a lance, such a flame generation, mobile working platform in front of the converter, blowing only into the surface of the steel. The same tuyeres can be used for blowing in oxygen and carbon powder, thus avoiding problems of penetration of the tuyere by molten metal, without extra problems of tuyeres wear, while keeping N2 injection a minimum, without blocking the tuyere openings.

Title: Electric motor for clock mechanism - has crystal oscillator oscillating blade magnetically coupled to rotor
IPC: H02K7/065
Filed: 1974-10-16
Abstract: The rotor of this motor can be a toothed wheel (2) made from ferro-magnetic material. An L-shaped permanent magnet (4) is mounted on a blade (1) so that it is oscillated by a coil (5) driven by a crystal-oscillator. It also causes the rotor to rotate by exciting its teeth. The blade is cantilevered from a mounting block and has the desired natural resonant frequency of oscillation. The drive frequency is reduced by a factor of f/2Q, where Q is the Quality factor of the blade. This gives automatic starting of the motor. The motor is suitable for timing mechanisms and has a simple construction.

Title: Anti blocking control using inertial mass - with time delay in poor grip situation to allow wheel to regain speed (NL150676)
IPC: B60T8/74
Filed: 1974-12-13
Abstract: The anti-blocking brake control has an inertial flywheel which is driven by a friction drive drom the wheels and which is fitted with inertial switches to monitor the retardation of the wheel. At the onset of wheel locking the brake force is modulated, and re-applied when the wheels run free again. Increases of poor road grip the system senses the poor grip through the friction drive and retards the re-application of the full braking force to allow the wheel time to regain its free running state again. The control has electric contacts which are each mounted on relatively movable parts of the brake which move together against spring pressure when the wheel is locked.
